PC3–Series: Absolute and Gauge Pressure Controllers with Remote Sensing

PC3–Series Absolute and Gauge Pressure Controllers with Remote Sensing measure absolute or gauge pressure at any point in your system, and control flow at a different point so you can maintain pressure exactly where needed.
  • Fast & accurate. Custom valve sizing and PID tuning ensure controllers reach pressure setpoints in milliseconds and maintain control with NIST-traceable accuracy to ±0.125% of full scale.
  • Versatile control. Control absolute or gauge pressure anywhere in your system, including areas where you cannot easily install a full pressure controller. Plumb the pressure port downstream for pressure or vacuum control, or upstream for back pressure control.
  • Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.

Device specs and customization options

Quick Specs
Absolute/gauge PC3-Series performance (most products)
  • Available ranges:
    • Absolute: max 0–3000 PSIA; min 0–15 PSIA
    • Gauge: max 0–3000 PSIG; min 0–2 inH₂O*
  • Steady state control range: 0.01% – 100% of full scale
  • Standard accuracy calibration, NIST-traceable: ±0.25% of full scale
  • Optional high-accuracy calibration, NIST-traceable: ±0.125% of full scale
  • Repeatability: 0.08% of full scale
  • Typical control response time: as fast as 50 ms
  • Warm-up time: <1 s

*Negative gauge pressure readings (to –15 PSIG) can also be included in gauge ranges.

Absolute/gauge PC3-Series operating conditions
  • Compatible gases: All non-corrosive gases
  • Operating temperature: –10°C to +60°C
  • Burst pressure: 3x full scale (1.5x full scale for 500 to 3000 PSI devices)
Device Ranges & Full Specs

Gauge devices are custom ranged from 2 inH₂O full scale to 3,000 PSIG full scale, and absolute devices are custom ranged from 15 PSIA full scale to 3,000 PSIA full scale. Most devices have a controllable range of 0.01% to 100% of full scale (valve dependent).

Valve sizing and PID tuning | Valve options

Your pressure controller may be customized with one of the following valving options to ensure optimal performance under your expected process conditions.

  • PC3 – small proportional control valve for flow ranges of 20 SLPM and below
  • PC3 with PCA designation – high-performance proportional control valve used for applications with higher pressures
  • PCP3 – small proportional control valve with the largest orifice (not available for corrosive configurations)
  • PCH3 – hammerhead configuration, which pairs two small valves working side-by-side as one valve
  • PCR3 – nearly frictionless large Rolamite proportional valve for flow rates of 50 SLPM and above

Accessories | Sold separately

  • Process port fittings and filters
  • Power supplies
  • Communications cables and conversion cables
  • BB3 and BB9 multi-drop breakout boxes
